The classification of fuel cells can be divided into the following categories according to the characteristics of electricity, battery structure, and operating conditions. Depending on the principle of electrification, it can be divided into indirect and direct. Indirect as the name is to convert the energy of the organic substrate into small molecule organic matter such as formic acid, methanol, methane or hydrogen, by chemical fuel cell, and generate current, a class of microbial fuel cells. . It is directed to directly converting its energy into a microbial fuel cell that directly oxidizes the organic substrate directly oxidized in the metabolic effect attached to the anode electrode. Although overall, due to indirect use of chemical fuel cells, it is directly used due to simplicity of direct structures, and the most cost of maintenance and cost is low.There are many kinds of fuel cells, and there are many classification methods. There are two main types: one is divided into direct fuel cells, recycled fuel cells and non-direct fuel cells according to fuel response. In response to once, the secondary battery also has a direct and regenerated fuel cell, the front battery reactant is discharged, while the latter can regenerate the product as a reactant. The third battery is a non-direct fuel cell, divided into two types. One is the processing of the organic fuel to convert it into hydrogen; the other is a biochemical fuel cell, a biochemical material produces hydrogen under an enzyme.
The further subdivision of direct fuel cells is divided into low temperatures, medium temperature, high temperature and ultra high temperatures according to their operating temperature. The corresponding temperature range is 25 -1 100`c, 100-5001, 500 --1000 ¡ã C and greater than 10001. The type of fuel cell used in different temperature ranges, wherein some fuels can be directly utilized, such as hydrogen. Organic compounds can be used after reforming, such as hydrocarbons, alcohols, etc. Carbon or graphite can also take into account M material. The nitrogen-containing fuel has been used is ammonia, off (NH, -NH, but also known as the ammonia). The oxidant used in all actual fuel cells is pure oxygen or air.
The most commonly used classification method is based on the nature of the electrolyte. The fuel cell is divided into five categories, alkaline fuel cell AFC (Alkaline Fuel Cell), phosphate ACI Cell, molten carbonate fuel cell MCFC (Molten Carbonate Fuel Cell), solid oxide fuel cell SOFC (Solidoxide Fuel Cell), proton exchange membrane fuel cell PEMFC (Proton Exchangemembrane Fuel Cell) Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
